WINDOW.

To all 'whomy 'it magi]v concern Be it known that we,l FRANK MESKR andJACOB BENQ, citizens of the United States e, and `useful Improvements inWindows, of

which the following is a full, clear, and exact description, referencebeing had tothe accompanying drawings, forming a part of thisspecication.

Our invention relates toa window, and

has for its object the production of av lireproof window structure whichis so const ructed as to be free to expand in the presence of a-highdegree of temperature. This feature is esirable for the reason that itallows the glass to expand freely, instead of breaking when subjected toa very high degree of heat.

' Our invention further includes several structural details to behereinafter pointed out.

Figure I is an outside view of our improved window. Fig. II is anenlarged vertical section, partly broken awa taken on the line'II-II,Flg. I. Fig. I I is an enlarged horizontal section, partly broken away,taken approximately on the line lIII--III, Fig. I. Fig. IV is aperspective view of a portion of the window, showing the jamb, sill, anda portion of the sasl?.-

Fig. Vais a vertical section taken approx mately on line V-V, Fig. IV.Fig. VI is a perspective view showing the interlock'between the linteland the top sash rail. Fig. VII is a cross section showin a device forconnecting the sash to the jam Fig. VIII is a view similar to Fig. VIImodified form of the sash rail.

In the accompanying drawings, J designates the window jambs and L thelintel, these parts being preferably of channel shape 1n cross sectiong/as seen in Figs. II and III. A sill S is secured to the lower ends ofthe jambs, thereby completing a rectan arwindow frame. Atv the lower endo each jamb are rivet stems 1, (Fig.

V), passing throufgh the sill, and upset,...

against the ttom ace of the latter.

The main sash frame comprises side ra1ls 2, arranged between the flangesof the jambs- J, atop rail 3 located between the anges of Specificationof Letters Patent. Application led July 1, 1912. Serial No.I 706,931.

sill S. The to' rail 3 is free yto move verti-v cally in the lintel, andit is notchedat 5, (see Fig. VI), to receive avertical lug 6 on one ofthe flanges of the lintel, the object being to, interlock the sash withthe lintel to prevent the sash from shifting laterally under ordinaryconditions and permit it ,to expandvertically when the window is.subjected to a high degree of heat. The

- bottom rail 4 of the maln sash is connected to the sill S by meanslwhich allow. the window to expand horizontally, said means comprisingpins 7 (Fig. V2, riveted to-the bottom sash rail and extending throughlongitudinal slot 8 in the sill.

Distance pieces 9, (Fig. V), separate the bottom sash rail I from'l thesi-ll'to provide a space through which water, particularly water ofcondensation, may flow Afrom/the inner face of the window to the outeredge of the sill.y The bottom sash rail 4 preferably has a down.- turnedflange 10 at its outer edge, and the sill is preferably a Z bar having-a web,

an upstanding flange at the inner edge of said web, and a downturnedflange at the outer edge of said web. It will be noted that the sill andbottom rail are so shaped as to produce an angularpassageway whichallows water to drain to the exterior of the building. j

The main sash frame preferably includes horizontal Ty bars 11. Thevertical sash bars 1,2form the sidewalls or jambs of a ventilatoropening, the top and bottom walls of said opening being formed byhorizontal bars 15 and 16, respectively. The'ventilator sash in theventilator opening comprises kside rails 17 and top and bottom rails 18and 19, said rails being connected by vertical and horizontal sash bars,as shown 111 Fig. I. `The ventilator sash is p1votallyconnected at 20 tothe vertical bars 12. f The panes of glass are preferably secured to theflanged sash bars by small angle bars 30 attached to said iianged bars.

Fig. VII shows the jamb. J and side rail 2 connected 'by a screw 32passing through. Van elongated hole in the side rail and screwed intothe jamb. This connecting device, loosely `fitted to the `side rail '2,does 'not in any way interfere with the vertical and horizontalexpansion of the sash.

The side rail 2 shown in Fig. VIII is in y the form of a channel havingan integral flange 33 engaging one side of the glass and an angle bar 30engaging the opposite side of the glass. 34 designates a bolt connectingthe angle bar 30 to the channel.

We claim:

1. A window structure, comprising a lintel, jambs and a sill; and a sashinterlocked with said lintel so as to allow the sash, to expandvertically, said sash being connected to said sill by means which allowthe sash to expand horizontally.

2. A window structure comprising a lintel, jambs, and a sill; and a sashextending into said lintel and jambs, said lintel having a lug and thesash being provided with a notch for the reception of said lug wherebythe sash is interlocked with the lintel to permit vertical expansion ofthe sash, and a slidable connection between said sash and sill allowingthe sash to expand horizontally. 3. A window structure comprising alintel,

jambs, and a sill; and a sash extending into L s'aid lintel and jambs,said lintel having a lug and the sash being provided with a notch forthe reception of said lug whereby the sash is interlocked with thelintel to permit vertical expansion of, the sash, and means forconnecting said sash to said sill, said means including a pin secured toone of said parts and slidably tted to the other part to permithorizontal expansionv of said sash. 1
